[0030] As Figs. 1-3As shown, the oil filling device of the oil-cooled motor of the embodiment comprises a container 1, an adjusting valve 3 and a connecting piece 4 connected in sequence, the cooling oil can be introduced and stored through the container 1, the flow rate of the cooling oil can be flexibly adjusted through the adjusting valve 3, and the device can be stably and tightly connected to the liquid injection port of the oil-cooled motor through the connecting piece 4. In the following, the specific structure of the above components of the oil filling device of the oil-cooled motor according to the utility model will be described in detail.
[0031] The container 1 in the embodiment is formed into a funnel-like structure, which can be formed into a circular table or a ladder table, etc., without specific limitation, as long as it can facilitate the export of cooling oil. The outer side wall of the container 1 is formed with a handle, so as to facilitate the workers to take the device and connect the device with the liquid injection port; in addition, the container 1 is formed into a transparent state and the outer surface is provided with scale lines, so as to realize the metering of the cooling oil, so that the oil quantity of the added cooling oil can be more in line with the actual working condition of the oil-cooled motor; further, the bottom of the container 1 is provided with a filter, preferably a fifty-mesh double-layer metal filter, so as to avoid the foreign matter from entering the oil-cooled motor.
[0032] As shown in the figure, Figs. 1-2 The top of the container 1 (i.e. its large diameter end) is formed with a liquid inlet, which is the liquid inlet of the whole device, and the bottom (i.e. its small diameter end) is formed with a sub-liquid outlet, and the adjusting valve 3 is in communication with the sub-liquid outlet. It should be noted that due to the specification limitation of the sub-liquid outlet and the adjusting valve 3, the adjusting valve 3 and the sub-liquid outlet of the container 1 in the embodiment are stably connected through a transition piece 2, which is formed into a tubular structure, the first end of which in the axial direction is connected with the sub-liquid outlet, and the second end of which in the axial direction is connected with the adjusting valve 3. Further, the transition piece 2 in the embodiment is stably connected with the sub-liquid outlet and the adjusting valve 3 by threaded connection.
[0033] In the embodiment, the adjusting valve 3 is set as a stop valve, so that the flow rate of the cooling oil can be flexibly adjusted according to the actual situation through the adjusting valve 3, so as to better adapt to different working conditions.
[0034] In the embodiment, as shown in the figure, Fig. 3As shown, the connecting piece 4 is formed with a sequentially connected lead-in section 40, sealing section 41 and connecting section 42, so that the connecting piece 4 is formed as a columnar structure. The inside of the connecting piece 4 is formed with a first cavity, which penetrates through the lead-in section 40 and the connecting section 42 to form a liquid outlet (which is the liquid outlet of the whole device) at the end face of the connecting section 42 away from the lead-in section 40, and the adjusting valve 3 can be connected to the lead-in section 40 by threads. In addition, the outer side wall of the lead-in section 40 is formed with an exhaust hole 400 communicating with the first cavity, so that when the cooling oil enters the oil-cooled motor, the gas in the oil-cooled motor can be discharged through the exhaust hole 400, thereby effectively increasing the filling efficiency of the cooling oil.
[0035] The connecting piece 4 is formed with a locking part that can be detachably connected to the liquid injection port, and when the locking part is connected to the liquid injection port, the device can form a passage from the liquid inlet to the liquid injection port to guide the cooling oil into the oil-cooled motor. Specifically, as shown, Fig. 3 The locking part includes an outer thread 420 formed on the outer side wall of the connecting section 42, which is adapted to the inner thread at the liquid injection port. In addition, the locking part also includes a recess 421 formed on the outer side wall of the connecting section 42, which can serve as a guide structure, and the recess 421 extends along the axis of the connecting piece 4 and penetrates through the end face of the connecting section 42 away from the lead-in section 40.
[0036] Correspondingly, the inner wall of the liquid injection port of the oil-cooled motor is formed with a protrusion, which has no specific structure, for example, it can be formed as a circular or square protrusion; when the connecting section 42 is inserted into the liquid injection port, the protrusion is located in the recess 421, that is, during the process of inserting the connecting piece 4 into the liquid injection port, the recess 421 moves along the protrusion, which can guide and position the connecting piece 4, and when the connecting section 42 is completely inserted into the liquid injection port, the protrusion is located at the same height as the bottom of the thread of the outer thread 420; and when the connecting section 42 is rotated, the protrusion can be located in the bottom of the outer thread 420.
[0037] It should be noted that due to the spiral structure of the outer thread 420, when the connecting section 42 is rotated to a certain extent, the protrusion will interfere with the outer thread 420 to achieve interlocking, that is, the stability of the connection between the connecting piece 4 and the liquid injection port can be further improved based on the threaded connection. Based on this technical effect, the number of turns of the outer thread 420 should be less (the specific number of turns is not limited), so that the interference between the long connecting section 42 and the internal structure of the oil-cooled motor can be avoided, and the workers can also conveniently rotate the device (without the help of tools such as wrenches).
[0038] It should be further noted that the size of the protrusion and the specifications of the outer thread 420 are not limited, as long as they can cooperate with each other to achieve the above technical effects.
[0039] In addition, the locking portion further comprises a sealing ring 5 sleeved on the outer side of the sealing section 41, the outer diameter of the sealing section 41 in the embodiment is smaller than the outer diameter of the leading section 40 and the outer diameter of the connecting section 42, so that the overall structure of the device is more beautiful and uniform. When the connecting section 42 is locked with the liquid injection port, the sealing ring 5 is located at the connecting position of the two, thereby effectively increasing the sealing performance of the connecting position of the two, so as to avoid the overflow of the cooling oil.
[0040] According to the oil-cooled motor oil filling device, the locking portion of the connecting piece 4 can stably install the device at the liquid injection port of the oil-cooled motor, and can effectively ensure the sealing performance of the connecting position of the two, thereby effectively avoiding the overflow of the cooling oil. Then, the cooling oil can be poured into the oil-cooled motor through the liquid inlet of the container 1, and the worker does not need to keep the stability of the device at all times, thereby effectively reducing the labor intensity of the worker. Further, the flow rate of the cooling oil can be flexibly adjusted according to the actual situation through the adjusting valve 3, so as to ensure the accurate filling of the cooling oil.
[0041] Finally, it should be pointed out that: the above-mentioned embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, but not to limit them, the protection scope of the present application is not limited to this, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily think of changes to the technical solutions recorded in the foregoing embodiments within the technical range disclosed by the present application, or make equivalent replacement to some technical features; and these modifications, changes or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and all should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
